次共變張量The interface behavior between essence and ethylene - vinyl acetate copolymer pallets was studied so that necessary data were obtained to guide the preparation of fragrant masterbatch. the adsorption type and wettability between essence and the copolymer pallets were analysed by measurements of fourier transform infrared spectrum, surface tension, contact angle and specific surface area. the technical factors affecting absorptivity such as the charge ratio, temperature, pressure and stirring speed were studied by series of adsorption experiments. the results showed that the adsorption of essence on the surface of ethylene - vinyl acetate copolymer pallets is physical in nature. essence couldn ' t moisten the surface of ethylene - vinyl acetate copolymer pallets absolutely, but it could be soaked into the surface of the pallets partly. adsorptivity could be increased by enhancing the temperature, pressure and stirring speed, but the extension of adsorption time had little influence on adsorptivity
研究了香精與乙烯/醋酸乙烯共聚物粒子之間的界面行為，以便為香型母粒的制備提供必要的理論依據.利用傅立葉變換紅外光譜、表面張力、接觸角及比表面面積等測定手段，分析了香精與載體之間的吸附類型和潤濕作用.並通過一系列吸附實驗，討論了配料比、溫度、壓力、攪拌等工藝條件對吸附量的影響.結果表明，香精在乙烯/醋酸乙烯共聚物粒子表面的吸附為物理吸附；香精無法完全潤濕載體粒子表面，但可以對其形成部分浸潤；提高溫度、壓力、攪拌速度可以增加吸附量，而延長吸附時間對增加吸附量貢獻不大Abstract : the interface behavior between essence and ethylene - vinyl acetate copolymer pallets was studied so that necessary data were obtained to guide the preparation of fragrant masterbatch. the adsorption type and wettability between essence and the copolymer pallets were analysed by measurements of fourier transform infrared spectrum, surface tension, contact angle and specific surface area. the technical factors affecting absorptivity such as the charge ratio, temperature, pressure and stirring speed were studied by series of adsorption experiments. the results showed that the adsorption of essence on the surface of ethylene - vinyl acetate copolymer pallets is physical in nature. essence couldn ' t moisten the surface of ethylene - vinyl acetate copolymer pallets absolutely, but it could be soaked into the surface of the pallets partly. adsorptivity could be increased by enhancing the temperature, pressure and stirring speed, but the extension of adsorption time had little influence on adsorptivity

（ 6 ）建壩工程荷載條件下河谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出：建壩后河谷的巖體應力量值明顯增高，同時左岸的張應力區的范圍及量值明顯減小，主應力的方向依然與模型的底邊界垂直；大壩建成后逐漸蓄水階段以及同時考慮本區最強地震力的作用等各種不同的工況條件時，滑坡體及壩體總體上仍處于穩定狀態；水位驟降時，在未考慮其他外力作用的情況時，滑體的安全系數將顯著降低。若考慮水位驟降及本區最大地震力的共同作用，壩體將在滑坡體下滑推力的作用下產生破壞；建壩后水平推力對右岸古滑坡體穩定性的影響分析可以看出，在最危險的工況條件下，壩體及滑坡體也將處于臨界狀態；在長期滲透變形的作用下，由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。Magnetic resonance diffusion tensor imaging : quantitative measurements on upper motor neuron of patients with amyotrophic lateral sclerosis
磁共振擴散張量成像對肌萎縮側索硬化癥患者上運動神經元病變的定量評估意義The results of data analysis show that : ( 1 ) there was a significant difference between perceived oc and expected oc, so was that between perceived ls and expected ls. moreover, expected oc and ls was more consistent with the claims of noninterference ; ( 2 ) variances at organizational and individual levels have different effects on perceived oc and ls ; ( 3 ) with organizational and individual variables under control, both the ideal models of oc and ls could explain the variances of oe. what made a difference was that in the former model, dimension of empowering had the strongest correlation with the oe, while in the later one, the dimension of generosity had the strongest correlation
資料分析的結果表明： （ 1 ）組織成員知覺與期望的組織文化與領導風格之間存在著明顯的差異，組織成員所期望的組織文化與領導風格與無為而治的主張更為接近； （ 2 ）組織水平與個體水平的不同變異對無為而治的組織文化與領導風格因素有著不同的影響效應； （ 3 ）在控制了控制變量的變異之後，無為而治的組織文化與領導風格因素對組織的效能水平有著不同的解釋力，對于組織文化而言，共享度對組織效能的影響力最為強烈，對于領導風格而言，樂善好施對組織效能的影響力最為強烈。分享友人
